How to interpret the output
Screening outputs are informational, not a diagnosis. Discuss concerning symptoms or measurements with an appropriate clinician.
Repeat measurements using similar conditions when monitoring trends. Numerical predictions can vary with input accuracy, measurement method and individual circumstances.
Limitations and responsible use
Metabolic age is an estimate, not a clinical measure. Focus on the trend (improving vs worsening) rather than the absolute number.
